Enabling --log-update

[Dan Hrabarchuk]

I need to track changes to my database while I'm doing a pg_dump.

I've found a reference to do this
http://www.arkeia.com/hotbackup/postgresql/ (see the second method).

It states that I need to put my database in the "mode --log-update"

I've tried to do this, but I keep getting an error saying that
--log-update needs an argument.

I can't find any documentation on this switch. Please help!

If I can't get this working my next alternative is to use either
http://gborg.postgresql.org/project/tablelog/projdisplay.php or
http://gborg.postgresql.org/project/audittrail/projdisplay.php

I need to have the database available while the dump is done.

Thanks is advance

No idea what that is but I have never heard of those flags. My guess is
that is a hacked version of PostgreSQL.

Does anyone have a suggestion on the best way to migrate data between
two slightly different tables? For example:

Table A
--------
id : integer
name : string
desc : string


Table B
--------
id : integer
name : string
date : date
summary : string

In this example, I would like to copy all the data from Table A into B,
using the desc column to populate the summary column.

Thanks,
Mike

One sql statement can solve this:

sql> isnert into table_b (id, name, summary) select id, name, desc from
table_a;

Thanks. I figured it was simple...

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match

Whoever wrote the Arkeia pages was very confused. I've communicated with
them previously, but no one was home.

My understanding is that those are MySQL flag settings, not PostgreSQL.
Whatever, they certainly don't work with PostgreSQL.

"Tracking changes" while you do a dump is exactly what PITR does in v8.0,
now in beta.

Best Regards,

Simon Riggs
